4 audio panels from 737 flight simulator built by Boeing look almost brand new!

Description

Up for action is 4 audio panels from a 737 flight simulator built by Boeing.  3 of the 4 panels have never been wired as seen in the photos. These were used in a procedural simulator and never placed in a aircraft.  These are basically brand new inside and hardly used on the outside, I have never seen panels like this before. The fourth panel is wired and one of the switches is broken, the part is easily replaced, but I have placed the broken peace in a bag so you can find the replacement or try to repair yourself.  This would be great original parts if building a Boeing simulator or just have them in unique Boeing collection.
If you have any questions let me know.
Good luck in bidding
